Investcorp, which acquired AMI along with its co-investors in 2005, however did not divulge the deal value and merely said "it was a well timed profitable exit".

This marks the second successful exit of the company in les than four months after the successful sale of American Tire Distributors.

Based in Ohio, AMI produces a wide range of exterior residential building materials including vinyl windows, vinyl siding, aluminum trim coil, and aluminum and steel siding and accessories.

"This is additional good news that we bring to our clients in less than four months after the successful sale of American Tire Distributors. This profitable exit is further evidence that Investcorp's value enhancement model creates growth and profitability," said Mohammed Al-Shroogi, Investcorp's president of Gulf business.

"AMI's position has been reinforced as the leading vertically integrated manufacturer and distributor of exterior residential building products in the United States and Canada."

"We have worked hand in hand with the AMI management team to develop the company's capabilities and sales volume to impressive levels, and we believe that this exit is well timed to serve the interest of our clients," Al-Shroogi added.
